Why does alcohol cause swollen hands?

I am a celiac, which means I have an allergy to glutton. Drinking anything with glutton causes my face to swell. MANY people suffer from celiacs and have no idea because in many cases the symptoms are mild and the body can also eventually get acclimated to certain foods where little to no symptoms will occur. This may not correlate to your situation but if stomach problems are coupled with your swelling after drinking beer, (not rum or tequilla as they contain no glutton) than you may want to get checked out.
